Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.

Abstract: Techniques for transmitting and receiving beamformed transmission(s) of a common search space of a DL (Downlink) control channel are discussed. One example embodiment that can be employed at a UE (User Equipment) comprises processing circuitry configured to: select a set of receive beamforming weights for a DL (Downlink) control channel; and decode one or more control channel sets from a common search space of the DL control channel, wherein each control channel set of the one or more control channel sets is mapped to an associated symbol of one or more symbols of a slot, wherein each control channel set of the one or more control channel sets has an associated transmit beamforming, and wherein each control channel set of the one or more control channel sets comprises a common set of control information.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

Abstract: An example method for wireless communication includes: receiving, by a wireless station, an uplink transmission from a wireless device of a set of two or more wireless devices; determining, by the wireless station, a need for a higher priority uplink transmission; determining, by the wireless station, a minimum cancellation processing time for the set of two or more wireless devices; and transmitting an uplink cancellation request to the set of two or more wireless devices based on the minimum cancellation processing time.

Abstract: Technology for a Next Generation NodeB (gNB) operable to encode downlink control information (DCI) for transmission to a user equipment (UE) is disclosed. The gNB can identify DCI for transmission from the gNB. The gNB can determine that a size of the DCI exceeds a defined threshold. The gNB can divide the DCI into one or more DCI segments. Each DCI segment can include header information to enable the one or more DCI segments to be assembled at the UE. The gNB can encode the one or more DCI segments of the DCI for transmission from the gNB to the UE.

Abstract: A user equipment (UE) or network device gNB can process or generate downlink control information transmissions for new radio (NR) systems or networks based on a compact DCI format. The DCI can include a grouped broadcast message for reduced signaling overhead that comprises random access response (RAR) message, a paging message, a system information block (SIB) message, another message information type, or any combination thereof. The DCI transmission can be determined as comprising paging information based on a direct indication in a physical downlink control channel (PDCCH) only or both in the PDCCH and a physical downlink shared channel (PDSCH) based on a flag field of the DCI transmission. Other configurations can also further reduce signaling overhead additionally or alternatively.

Abstract: Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).
